Adding inverse periods in a Basic Program.

[Nickolasgaspar]

I am working on a basic list and the following line writes the following.

1015 REM NEXT LINE CONSISTS OF FOUR CONTROL N'S, FOUR INVERSE PERIODS, AND FOUR INVERSE SPACES.

Any ideas on what "inverse periods" are and how I can insert them in my list (Altirra 3.90)?

The next line is the following:

1020 FOR X=4 TO  8:POSITION 2,X:? #6;"---____--":NEXT X: POSITION PC,PR-------:? #6; ' #"

                                                                 sss4c+nss                                       7spaces

 

I would really appreciate any help

Inverse on the Atari keyboard is the fuji symbol.  I believe in Altirra, it's the "End" key.  Press that, and then the space or period.  The inverse space will show as a solid block, and the inverse period will be a solid block with the period missing.

 

Just as reference.  The Atari only has 128 character fonts.  This gets repeated in "inverse mode", where bit7 is high.
